Kaposi'S sarcoma of the stomach and duodenum in human immunodeficiency virus infection.

Kaposi's sarcoma (KS) of the upper gastrointestinal tract without extensive cutaneous disease is uncommon and usually asymptomatic. Herein, the case of a 37-year-old man who presented with iron deficiency anemia is reported. A colonoscopy was unremarkable and upper endoscopy revealed multiple raised, hemorrhagic, plaque-like lesions throughout the stomach and the small intestine.

Giant ulcerated lipoma of the colon causing iron deficiency anemia successfully treated with endoscopic ultrasound-assisted resection.

Colonic lipomas are frequently small and asymptomatic. Giant colonic lipoma (GCL) is an uncommon finding at endoscopy, and ulceration with occult blood loss leading to iron deficiency anemia (IDA) is even rarer. The choice of therapeutic procedure to treat symptomatic GCLs has been controversial.
